That still leaves the oddities with a second subscript:

  typeset -n ref='arr[2][1]'
  arr=( one two three )
  echo $ref
  echo ${ref}
  ref=Z
  typeset -p arr

Only case where the second subscript works is when ref is in braces.

That'd work. There's been a few times when I've wished (k) and (kv)
would work for normal arrays. the former is just {1..$#arr} but would
work in nested expansions.
